Trident TD, page-12

I can't see them going into a TH because they had got part way into Trident and found nothing at that time. If shareholders are watching the drill depth closely enough the lack of news is probably alarming and offers them a fair chance to get out the further it proceeds. A Trading Halt completely denies you that chance if it's a duster.

I think it more likely they have found something and therefore have gone into a TH. But I guess Monday will tell.
